Mechanical, Drop Load Impact and Fatigue Properties of Silane-treated Chitosan and Waste Leather and Areca Fibre Epoxy Composite

The major objective was to study how adding silane-treated CCP and a hybrid blend of fiber and leather would improve the epoxy biocomposite's mechanical and ballistic resistance. Fiber and tanned leather were treated with silane and composites were made via the hand layup method. The fibre and leather was laid by two different sequence and the composites were cured at elevated temperature. Results revealed that the Areca/Leather/Areca (ALLA) stacking sequence of 1.0 vol. % of CCP significantly improved the composite's mechanical properties. The low-velocity impact capability was significantly increased by the hybridization of fiber and leather, reaching 11.8 J for untreated reinforcements and 12.44 J for reinforcements treated with 1.0 vol.% of CCP. Similarly, the maximal fatigue life count of 36,131 was achieved by adding 1.0 vol. % of CCP to the ALLA sequenced composite. The research indicates that the best outcomes are achieved by using hybrid layup configuration of Areca/Leather/Areca and silane-treated 1.0 vol.% CCP. These composites with increased ballistic resistance and toughness could have potential utility in domains such as automotive industries, defense and structural, where high toughness is required.
